A colleague from the Czech-Slovak 911 movement have sent me the link to a new video (whose original intention was to debunk another debunkers video about WTC7)

But in fact it shows much more than just counterarguments against the debunkers video.

It shows that from the North tower were during the "collapse" clearly visibly ejected large chunks of its core - ripped in pieces of size of several floors, weghting probably at least hundreds of tons - to a realy considerable distance. - They were in past notoricaly confused with the perimeter columns - but perimeter columns were much thinner and mounted with much narower distances. The column distance in chunks - they can be seen in the video - compared to the north face 64m reference, is at least 4 meters, while the distance of the perimeter columns was 1m. The beam structure on the video looks like literally fitting in the proportions of the core mount - so the assumption it is the chunks of core, not the perimeter, looks like one very well supported. What force ripped the large core pieces lateraly out of the building? A Gravitation??

At 5:20 p.m. on the evening of September 11th, 2001, the Salomon Brothers Building, also known as 7 World Trade Center (WTC7), the northernmost building on the World Trade Center complex, uniformly collapsed in 6.5 seconds. It produced a rubble pile with a radius similar its original dimensions and approximately seven stories tall [1].

The Roman Candle collapse complete with side bursts. Just why in the hell would the Iranians need a nookular weapon anyhow? Just take an old aluminium tube, fill it with 10,000 ltrs of kerosene and boom....There goes Manhattan!!
